技术领域 Technical Field

[0001] 本发明涉及半导体工艺清洗设备领域，尤其涉及一种控制化学液温度的装置及方法。 [0001] The present invention relates to the field of semiconductor processing equipment cleaning, and more particularly to an apparatus and method for controlling the temperature of the chemical solution.

背景技术 Background

[0002] 在传统的半导体清洗工艺中，针对进入工艺腔室中化学液粘度不一致的情况，在工艺过程中，通过加热器加热到一定温度的化学液流经到各个工艺腔室的路径不同，因而到达各工艺腔室的化学液的温度和粘度不同，不能够很好的满足工艺要求，对清洗的效果带来一定的影响。 [0002] In the conventional semiconductor cleaning process, the viscosity of the liquid chemical for inconsistencies into the process chamber case, in the process, is heated by a heater to a temperature of the chemical into the liquid flow path through each of the different process chamber, thus reach different chemical liquid temperature and the viscosity of each process chamber, can not satisfy the technical requirements, some impact on the cleaning effect.

[0003]目前的工艺方案中，都只在主管路上对化学液进行加热，加热后的化学液通过多条并行管路进入到各自的工艺腔室。 [0003] The current process scheme, only in charge of the road to the chemical solution is heated, the chemical liquid was heated by a plurality of parallel pipes into each process chamber.过程中，各个工艺腔室与加热器的距离有远有近，两者之间由于管路长度的不同，散失的热量以及水分的挥发存在一定的差异，这就使得流到每个工艺腔室中的化学液的粘度和温度的一致性得不到保证，不能很好的满足工艺要求，另一方面，由于加热器和工艺腔室之间还有一些距离，当化学液到达工艺腔室时，由于热量的散失化学液的温度会有所降低，导致实际的化学液工艺温度与加热器控制的温度有较大的偏差，不能实时反映当前的工艺温度。 Process, the distance between each process chamber and a heater that are far and near, due to different line lengths, there is a loss of heat and moisture volatilization of certain differences between the two, which makes the flow of each process chamber The chemical solution viscosity and temperature uniformity can not be guaranteed, can not meet the technical requirements, on the other hand, due to the process chamber between the heater and some distance, when the chemical liquid reaches the process chamber Since the temperature of the chemical liquid heat loss will be reduced, resulting in an actual chemical liquid process temperature and the temperature of the heater control a large deviation, it does not reflect the current real-time process temperature.
